COMMENTARY | Probabilistic genotyping software has helped forensic labs close more cases and exonerate individuals wrongly accused of a crime.

The development and implementation of forensic DNA typing more than 30 years ago has been a boon to law enforcement, the judicial system and society. The unprecedented expansion of biological evidence that now can be analyzed has led to more arrests, convictions, exonerations and re-openings of cold cases. This success, though, has created an increased demand and additional focus on processing more challenging samples to assist investigations.
